Description

Plate manufacture method and core rod thereof
Technical field
The present invention relates to the particularly manufacturing of filled board of plate undertaken by fiber reinforced plastic materials.In this connection, can consider to bear the plate of top load particularly, bridge plate for example, it must bear the full payload that is made of following summation: the weight of bridge self, the weight of road vehicles, and the local load that is caused by wheel and analog.
Background technology
Utilize the method for traditional this plate of manufacturing, at first in having the mould of the desirable complementary shape of bridge plate for example, generate shell.This shell is made of fibre reinforced plastics, as being full of fiber connecting plate or pad and making with resin.Core rod is arranged on this shell, constructs second shell afterwards.After these parts are by correct assembling, promptly obtain to be used for the further semi-finished product of handling.
One of defective of this method is complicated.The method of being discussed comprises four steps,, makes first shell that is, makes core rod, and core rod is placed on first shell, makes second shell and second shell is put on the core rod.The very time-consuming reason of this method why that Here it is.Another defective of this method is to exist the interface between core rod and the shell not exclusively to become wet danger in the adhesive adhesion process, and this may cause entrained air, and this intensity and hardness for sintetics all is disadvantageous.
Summary of the invention
Therefore the method that the purpose of this invention is to provide a kind of more effective and more reliable manufacturing fiber reinforcement plate.This purpose realizes by following step:
-placing modules on mould, but described assembly comprises core element and along the material connecting plate of the core element and the filling of extending between core element, described assembly comprises first side and second side opposite with described first side,
-in the mode of sealing described assembly is enclosed in below the cover layer with respect to mould,
-introduce at least one injection material import, described import ends at first side of described assembly,
-connect by the space and the discharge pipe line of described cover layer and the sealing of described mould,
-via described import injection injection material on the bottom side of described assembly, and injection material is moved between core element along the path that is formed by described material connecting plate,
-under-voltage by means of with the position of the pressure varying level of described import termination position discharged air and/or gas via discharge pipe line from the space of sealing.
Utilize the method according to this invention, the different piece of filling plate is concentrated in the same manufacturing step.In this case, two shells and core rod are formed simultaneously and are attached to one another.In addition, if injection material directly is fed to the plate bottom side, almost without any the danger that forms entrained air.The front of injection material moves up gradually and forces any air to be sneaked in this process and other possible gas moves upward and shifts them onto the injection material front, so these can be discharged in reliable mode.But, injection material is supplied to the bottom side not necessarily.Alternately, material also can be provided to upside, so that it moves down gradually.In this case, may have some air and sneak into, but this is not to use for all to constitute problem.
Preferably, use the particularly block core rod of prismatic core rod.The material connecting plate can stride across the upside of a plurality of core rods separately, between two adjacent core element separately and stride across or extend along the bottom side of a plurality of core rods.By this way, acquisition is at the plate that has fabulous characteristic aspect the resistance of overall strength and hardness and opposing local load.Especially, the method according to this invention comprises the steps:
-a succession of prismatic core rod is set in parallel with each other,
-provide injection pipeline, described injection pipeline to stride across mould and on described a series of first side, extend, and described injection pipeline is oriented orthogonal to core element, and described injection pipeline is connected to import.
Injection pipeline has the advantage that injection material can be evenly distributed with respect to the vertical extension of core element on the width that strides across adjacent model element.This is to make the front of injection material with the first mobile up and down gradually respectively measure of equally distributed mode.Yet the part of material connecting plate may reside between the different core element.For the width that can the stride across adjacent core rod injection material that distributes equably, even under those situations, the method according to this invention preferably also comprises the steps:
Provide passage in the-material connecting plate part of between adjacent block core element, extending respectively,
-injection pipeline that passes a succession of material connecting plate part internal channel that aligns is provided respectively.
This means in the core rod construction process to have the core element of material connecting plate above one of every placement, all manufacturing hole in corresponding material connecting plate part.For this purpose, must insert the injection pipeline that passes respective aperture separately partly fits together.According to the present invention, this realizes by following step:
-the injection-tube line segment is provided, its length dimension equals the gauge of core element,
-after having placed core element and above described core element, having arranged related material connecting plate, the injection-tube line segment is inserted passage in the described material connecting plate, and described injection-tube line segment is attached to the injection-tube line segment of placing previously or is attached to inducer.
It also is very important that air of being replaced or gas can be discharged in the mode of routine, so that can not form local pressure reduction, local pressure reduction can be upset the formation of the front of evenly advancing.For this purpose, this method also comprises the steps:
-discharge pipe line is provided respectively, make it laterally stride across second side of core element and stride across the material connecting plate part of extending along core element,
-the centre between two injection pipelines biasing discharge pipe line respectively.
The one or more discharge pipe lines of lateral arrangement have guaranteed, see the air of being replaced and/or the rule of gas and discharge uniformly on the width of core rod.Discharge pipe line has guaranteed that with respect to the offset position of the inlet line that is positioned at following or top air or gas are more or less identical for all core rods along the path of its discharge, from inlet line.This has prevented to cause the generation of the irregular short-circuit flow that forms previously.
Emphasize that as top it is very important that injection material rises once more in more uniform mode between core rod.In this connection, can take to guarantee tranquil front and steadily several how other measures of the formation of percolation.By first selection, mention following step:
-core element is provided, it has the groove that extends perpendicular to injection pipeline respectively and is provided in the sidewall channels that is parallel to described groove extension in the sidewall in its first surface, and groove in the first surface and sidewall channels are separated each other,
-make injection material from the groove lateral flow that is arranged in basal surface via the material of material connecting plate up to entering sidewall channels.
Utilize core element, the groove of injection material initial flow in first surface that is to say, usually on the length direction of each core rod.When this groove during by filling fully, injection material is only further to flow by leaving groove.In this stage, the material of injection material contact material connecting plate causes throttle effect, has therefore guaranteed that the material of described material connecting plate is got wet along the whole length of groove.Then, injection material enters in the sidewall channels via the material connecting plate, therefore is activated at the real front that forms on the direction up and/or down.
Core rod can also play an important role aspect discharge gas or the air.This can realize by following step:
-core element is provided, each core element has the slot part of the second surface that is arranged in core element, they are by separated from one another and end at the opposite cross side of described core element, described slot part is parallel to the residing sidewall of sidewall channels, all slot parts and described sidewall channels are spaced apart from each other
-injection material is flowed until entering slot part via the material of material connecting plate from sidewall channels,
-respectively discharge pipe line is positioned between the end that faces with each other of the slot part in the second surface of described core element.
Injection material leaves the slot part that arrives and enter the core element second surface from sidewall channels and takes place via the material of material connecting plate part once more.In this case, realized the even distribution of injection material once more.Groove in the core element second surface does not extend to discharge pipe line, the material of the material connecting plate part at core element top so that injection material must at first be flowed through before arriving discharge pipe line once more.
Utilize large-scale relatively structure, as the example of bridge, the problem that injection material can not penetrate well along the edge of assembly may take place usually.This can prevent by following step:
-at least one edge of assembly at least one auxiliary injection pipeline is set,
-in the phase I, the injection injection material makes only flow through those injection pipelines of horizontal expansion of injection material,
-in second stage, injection injection material again makes the injection material auxiliary injection pipeline of flowing through.
At this on the one hand, the further improvement to the injection material injection can obtain by following step:
-round assembly annular auxiliary injection pipeline is set,
-discharge pipe line that is positioned at the center with respect to annular auxiliary injection pipeline is provided,
-the auxiliary suction pipeline is connected the position that is used for injection material is supplied to the inlet line top of assembly on the side of assembly,
-by means of the hypotonicity limiter described aspiration line being connected to inlet line, described limiter has to the low flow resistance of air and to the high-drag of liquid transmission,
-with the position of the opposite side of the residing side of import, the part that the aspiration line extraction unit from injection pipeline is divided the injection material and only extracted injection material out,
-via discharge pipe line gas bleeding and/or air there.
Extract injection material out from the auxiliary suction pipeline and have following advantages: the infiltration of the gas the assembly on described side is held prevention.In fact, have been found that on a side opposite that via short-circuit flow, the gas prioritised transmission is to the residing assembly of main discharge pipe line center with an import side of living in.Now injection material is pumped to limited degree, thereby before air enters assembly, collects air, prevented the generation of entrained air and still can realize the high-quality filling by the injection pipeline place on described opposition side.
The invention still further relates to the core element of using with aforesaid method.This core element is block shape, have first surface, with first surface opposed second surface and opposed facing vertical side and opposed facing transverse side, wherein, described first surface is provided with and is parallel to the succeeding vat that extend described vertical side.
Described vertical side can further be provided with succeeding vat, described succeeding vat between first surface and second surface, extend and by with first surface in groove separate.Described second surface can also be provided with two slot parts spaced apart from each other, and each in them ends at the transverse side place, described slot part by with described vertical side in groove separate.In another embodiment, described first surface can be provided with opposite groove, and each groove and transverse side groove adjacent and that be arranged in described first surface ends at described groove.Injection pipeline can be housed inside in the described groove.
